I don't think any of our loyal readers will be surprised when I admit that I enjoy reading or listening to Douglas Rushkoff. Not necessarily because I subscribe to each and every one of his views, but rather because I find his view of the possibilities for the world inspiring, even when he's decribing the world at its worst.
Last year Rushkoff delivered a speech to the Pop!Tech 2004 (Renaissance Prospects) gathering. You can download the MP3 of his address below. In it, Rushkoff looks at a topic he's been pursuing quite a bit of late; the idea that the world is on the cusp of going through a new Renaissance rather than a Revolution. It's an interesting 45 minutes where he asks his listeners to think a little outside the norm.
